A frequency domain approach for blind identification with filter bank precoders

It is well-known that filter bank precoders can be used for blind identification as well as equalization of FIR channels. In this paper we introduce a new blind identification scheme which directly identifies the frequency domain equalizer coefficients. The precoder redundancy required for this is the same as in the earlier methods. But the proposed method offers simplicity. For example closed form formulas are involved rather than iterative computation of annihilating eigenvectors as in earlier methods.
